The suggestion was that the VO logging interface and functionality not
be provided by individual services, but by some centralized site logging
service (specific to VO, not httpd logging or some such)) which the
domain-wide VO log harvestor can access.

This is what was meant by a "centralized logging service" for a site.


I still think it would be good if low level infrastructure capabilities like
service registration, logging, heartbeat, etc., could function independently
of complex high level data management functionality such as VOStore.
